To all whomit ntay I "'B "tknown; that I, HnNRir P. Ronnn'rs, of a Boston, in thecounty of Suffolk and State of Massachusetts, have invented certain new andiuseful Improvements in- Beating'and Devices, of which the-following is a specification. Y 4

This invention relates to an improvement- 1 :11]. beating and mixing devices. I The object of the invention'is to provide a device which shallquickly and effectively beat up. and mix',.be lilre, so. as to produce a smooth, well blended m1xture,'i n which allthe ingredients arefinely divided and thoroughly mixed, and

the whole. mass lightened andaerated.

- Qlhe-.devi ce-li'sprimarily'intended foruse in' places where beverages are dispensed, although some of its features are "adapted liquids, and the like a 1 ith'the aboveobject in view,- the invention consists in the beating and mixing de-" vice hereinafter. described and particularly 2'5 defined in the, claims, the advantages of" which will-be obvious to those skilledin the art from the followingletaileddescription..

j The. invention will clearly understood from an pection ofithe accompanying 'draw gim which 1 Figure lis a side elevation of-a'n illustrative embodiment of the invention; Fig. 2"is a front elevation of .the same; Fig. 3 vis area r elevation'with parts broken away tov show the interior of .thestandard and plunger; Fig.- 4' is =ahorizontal section on an enlarged scale, *taken on the line Fig. 1, showing the upper arm of the stationary'guideframe for the 're-' .40; 'ciprocatory stemi'Fig. fi-isahorizontal sec- 'tion taken on the line .-5 in Fig. 1; Fig. 6.

is a verticalsection through the dasher taken on the line 6-6 in Fig; 5; and Fig. 7 is a perspective detail view of the-connectingrod 451and ball socket for the stem of the dasher.

" As illustrated in the-drawing, the present embodiment 'ofthe invention comprlses a hollow standard 10, preferablyrectangular' in cross-section, mounted upon-a base 12, or; other :suitable. support, by means of ascrew 14, or 'inany. other approved manne'rj'. A; telescopingsupport or plunger 16 fits the terior of the standard '10,.the latter acting verages, eggs, and the .screw'20' which projects into the interior of raise the plun'gerso that a glass orother con Fig. 2. The plunger 16 is held in its lowered poing-fiange 27 on the'exterior of the. standard 10. The catch 22'is provided with a finger hold, preferablyin the form of a loop or eye 28, by means of which the latch may be manually operated to release the lip 26.from

the flange '27, whereupon the plunger will be spring 30 is provided, whichwengages .the' upper end of the catch 22, and tendsnorwithrelation to the' ledge 27. I v The upward movement of the plunger16 vided in the. front sideof the standard 10 This stop moves-along the front face of the ledge or projecting flange 27 in its upward movement.

the parts are in'the position shown in 'th jdrawijngr 'A.f oramin'o,u's dasher 34, pre

series of apertures 35, and' a pluralit of inclined and curve d in 'the'form .of propeller blades, so that Whemthe dasher'ls to out, beat,f and-mix; thecontentsoffthe receptacle whiel i itii's operated, and. to thoroughly aerate-and agitate the contents without spatt'e-ring orlspilling' thesame.

The caster-ails secured to the lower nd the plunger. This-spring tends normally to' automatically raised by the spring 18. A,

tainer 21 maybe placedln position or re moved from the device, the 'das'her being then raised to the dotted line position shown a sitionby 'a catch 22 pivotedat 23 in ears 24f,

which projectlaterally from the plunger.

. The catch 22 is provided with a lip 26 which engages the underside of. a ledge or projectunder the influence of the spring 18, when; I

the. catch 22 .has been released, is limited by the stop 32 secured to the plunger 16 andprojecting throughan-elongated slot -33 prostandard 10 and adapted to engage the During the beating and-mixing-op'eration' erably of sheet metal, is provided with a .recipro'cated androtated' the blades operate of a spiral stem'QS, which preferably subs't-a'ntially rectangular in cros's-section,and

, is adapted to pass freely'through a control ling aperture 39 formed in the lower arm 40 of 'a. U shaped guide frame 41, secured to theplunger 16. 'The aperture 39 is also mean,

. gular, andthereciproc'ationof the stem 38.

p therethrough causes the latter to oscillate.

Thestem 38 also pas'ses'through a circular guiding aperture $2 in the upper arm 43 of 7 the guide frame ll, whereby said stem is steadied. The uppenendof the stem 38 is' aball-and-socketconnection. p 1

The ball .44 isheld inaspherical socket, preferably formed by two plates 45,- 46,

provided witha-spherical ki'ob' or ball 44 ofv which are se'euredtogether'bya screwf ii, The plate '46 is provided with an elongated thereon, if desired.

- slot 48,'whi ch is adapted to receive a lug 49 on a bar 50. A screw '51 clamps the plate 46-- and the bar 50 together, the twoconstituting an ad ustable connectingrod, whereby the upper and lower limits of the dasher 34 may be regulated. It will be understood how- .i ever that the connecting rod may be in'adeof" a single piece of-metal and the 'socketformed The bar 50 is pivotally connected .at its upper end to a crank arm 52 on a shaft-54,. suitablyjournaled in theupp'eren'd of theplunger 16. ,AI'pinion 56flis fast on the shaft 5e and meshes with a gearl57,vvl1icb,'-is fast. on a shaft-58 also journaled in the plunger 4 16. An opcratingcrank 60.is ,fast on the shaft 58 and is provided with an operating handle '62, by means :of which the,:.fmecha-;

nism is operated. By-turningthe crank .60,

the gear 5.7 rotates thepinion '56,- whereby the crank 52 is rotated to raise and lower the connecting rod attached thereto. Thus the' spiral stem 38 1S ,reciprocated and oscillated,

and with it; the dasher 34. 'The' dasher is thus given a rapid combined oscillatory and reciprocatory motion, whereby the propeller blades cut, beat and commingle thecontents of the receptacle 21, and. these contents are also repeatedly forced'through the apertures and around the periphery-ofthe dasher, hen the beating and mining operation is' completed, theli'p 26- of the catch 22isreleasedfrointheledg'e 27, whereupon th spring 18 automatically f raises-th plunger 16 and therebywithdraws the dar tier from the rece )tacle, so that the lattermay be quickly removed andreplaced by another.
